Bilirubin and the brain: Jaundice-associated pigment may protect against malaria

Scientists say they have new experimental evidence of a novel role for bilirubin, a natural yellow pigment found in the body, in protecting humans from the worst effects of malaria and potentially other infectious diseases. The findings could advance the search for drugs that mimic the pigment bilirubin, or deliver it to the body to help protect people from severe forms of some infections.
